The invention relates to containers -and more particularly -shipping-vessels, suchfas barrels or the like used for the transpontationlandstorage ofl corrosive, tastesensitive -and valuable-lling materials-In'order to dispense withtheuse `of expensive materials, namelyaluminum," copper, pure nickel," noni-corrosive steel'rnetalfalloys'andfthe like, containers have been'produced which consist of an innersleeve orshell and outer bracing elements. -The' outer-bracing elementsreplace the previously employed louter container, but, it lwasascertained that the youter bracingelements (steel reinforcements) werenot! sucienft ltoprotect'the inner container made of expensive materialfrom external destruotive'actions. f Hence, the wall of 'theinnercontainer had .to be made stronger, and, the cost of the same exceededsubstantially the production costs of the outer container. To the extentthat enclosures of synthetic material, cardboard, rubber and the likewere used for a thin-walled inner-container or shell, the Wall thicknessof the outer envelope or enclosure, in view of the high resistanceVrequired by the entire container was such that the-increased costofmanufacture was prohibitive. This is especially true of'enclosures ofa` synthetic material as suitable synthetic materials are tool expensiverespecting purchase and processing for oontainers.

Furthermore, a container has been heretofore provided which consists ofa barrel having a metal or` synthetic material lining and the foil is inthe nature of a bag which is inserted into the outer container. v v

Outer containers made of steel do not, however, satisfy the requirementssince in filling and dispensing corrosive materials, contact of theiiillingv material with the outer container cannot be avoided. Thisresults 'in a premature destruction of the outer container by acorrosive action and the inner container or lining fails to protect theassembly against damage as' cracks and the like are easily formedtherein.

The above and other objectionable characteristics are overcome accordingto the present invention. Toproduce the present invention, there isprovided an inner sleeve or shell, preferably of corrosion-resistantmetal or homogeneous synthetic material and the wall thickness or crosssection is quite thin. Bnacing reinforcements of a less expensive ornon-corrosive resistant substance which are subjected to externalmechanical stresses are provided for the inner sleeve and suchreinforcements are in the nature of head rings and annular hoops bymeans of which the container can be rolledalong a supporting surface. Alayer of synthetic material is applied, preferably in a liquid stateTorA in a state permitting kneading throughout the entire assembly.After thislatter layer has set or hardened, a'V rigid iand insolublejoint or h l the assembly.

Moreover, it isalso possible that the reinforcement can be lirst placedon the inner sleeve or shell and the cavitiesof the reinforcement filledby pouring an ad-` hesive filler therein. ,After the filler is set, itjoins the reinforcement and inner sleeve.

j" Anotherf embodiment includes the concept vthat the lled'headreinforcement, the bottom bunghole and the 'wall yare applied lto the'inner sleeve, and, ythe outer sleeve or shell ofsynthetic material isthe'n secured. "Atthe mid-zone and atboth sides, the syntheticcoating isWider' Yand thicker thereby achieving'the additional rigidity.

1 To 4avoid deformation`- of :the inner sleeve or shell,

prior fto or'during application of the synthetic material, or duringpouring, fthe inner sleeve is filled with a gaseous or liquid medium,and, safety means regulating the pressureareemployed; y Y. I l i 'yBetween the reinforcement andthe inner sleeve, a layer of syntheticmaterial `in a liquid state or a state allowing kneading, may be appliedso that after setting, a rigid, insoluble medium results.` Y

The -synthetic material can be applied as an outer sleeve in one or morelayers and intermediate the layers, ller or bracing layers ofjminenalfiber, wrapping paper, brous substances, textiles or /wire netting canbe arranged. f f' f The synthetic material canI becolored -by theaddition of the desired color medium Vvand the drying or setting can beaccelerated by'a' convenient heat treatment.

Between the Ithin-walled innersle'eve or shell and the reinforcements, asynthetic substance can be positioned,-

and, this is especially true of containers in Which the reinforcementsare hollow rolling hoops and'head hoops.) In addition, reinforcementssuch as aibunghole' ange, name plates, advertising plates `and the likecan be united by the use of synthetic materials without the employmentYof other means.

The outer wall of the container can be bulged, and, hollow hoops havingla liller can be provided at the ends and the side wall with-the innersleeve and reinforcements secured together by an louter sleeve ofsynthetic material. At the upper end and in the mid-zone thereof, thesynthetic layer is-thickened and'surrounds the bunghole unit carried bythe inner sleeve, and an annular ring also cooperates with the bungholeunit to additionally retain suchrunit.

The lower end Aof the inner sleeve-or shell can be arched and surroundedby an arched synthetic coating. Adjacent to the -bung-hole unit carriedby the side wall ofthe inner shell, the outer synthetic layer isthickened to compensate fo'rthe bung-hole unit and adapt the same unionis effected between the reinforcement and the inner ,sleeve or shellthereby,attaining ,the required mechanical resistance necessary by thelcontainer. v i v Lt is also possible to produce a container havingequivalent characteristics by placing the inner sleeve, preferablycentrally in aniold andthe intermediatespace bounded section of one formof the invention. '1 t fingered MayV 9, 1961 Figs. 2 and 3 arefragmental views in vertical cross section of further forms of theinvention.

Fig. 4 is a vertical sectional view of a fragment of the upper end of acontainer illustrating the mode of reinforcing the bung-hole unit. v

Fig. 5 is a vertical sectional View of a barrel having bulged side wallsconstructed in accordance with the Vinvention.

Fig. 6 is a fragment of -a barrel with bulged side walls showing invertical cross section, a further form of the invention and,

Fig. 7 is a vertical sectional view of yet another form defined by aninner shell and a cast outer wall.

As shown in Fig. 1, a container C is defined by an inner sleeve of shell1 of very thin ycross section and the shell is provided with an annularhollow hoop 2 and hollow end or head parts 3. The hoop 3 allows thecontainer to be easily rolled on its side along a surface while the endparts permit the ready movement in the vertical or substantiallyvertical position.

Intermediatek the inner shell 1 and the end parts 3, there is iirstapplied a synthetic material 4 and this material layer defines a jointtherebetween. An outer relatively thin-walled layer of syntheticmaterial 5 is -then applied to the assembly, with the material either ina liquid state or a state allowing kneading. When the layer 5 has set orhardened, it surrounds the sleeve or shell 1 together with the hoop 2and the end parts 3 thereby holding the respective parts together.

Together with the reinforcements and the inner sleeve A 1, the syntheticlayer 5 includes a substantial portion of the supporting member, and,this portion can be increased in the manner shown in Figs. 2 and 3.specifically, this is effected by arranging between two or moresynthetic layers 5 and 7, an intermediate layer or layers 8 of therequired thickness, and, such intermediate layer can be fibrousmaterial, paper, cardboard, mineral fiber and the like. In addition,less expensive material, such as wire netting of ifine or coarse meshcan be employed for the intermediate layer.

In Fig. 4, there is illustrated a manner in which a bung-hole unit isattached to the container. It will be More seen that an internallythreaded ring 9 of the same matev rial as the shell 1 is reinforced by abung-hole ring 10 which is covered by a layer of synthetic material :11thereby permanently connecting the parts with the inner shell 1, and,the connection is improved by interposing a synthetic layer between thesleeve 1 and the ring 10.

Fig. 4 further shows how a name plate or an advertizing plate 12 can besimultaneously secured to the assembly.

It will be appreciated that the container is very sturdy, presents asmooth surface, and, if desired, the synthetic layer can be colored tosuit requirements of the purchasers. Furthermore, valuable material issaved, and, depending on the use of the container, a considerable rangeof synthetics can be employed. The synthetics may be either very hard orelastic, such as PVC or polyester bases.

In Fig. 5, there is depicted a barrel B wherein the side wall is bulged,and, is of a type commonly used for malt beverages, such as beer andale. In this form, a thin-walled inner shell 13 of metal or syntheticmaterial is provided at its ends with vhollow reinforcing rings 14 ,andthe cavities of the rings contain a filler material 15. The inner shell13 and the rings 14 are entirely covered by a layer or sleeve 23 ofsynthetic material and in the mid-zone of the assembly, the layer isthickened to provide a band 16 and adjacent to the ends, the layer isthickened to form bands 17 which are slightly less vin height than ithevcentral band 16. The dimensions of `the bands 16 and 17 are-determinedin accordance with the stresses which will beimposed `on the b arrel,and, .the wide ,band 16 is primarily Vused in connection with beerbarrels.

A synthetic coating '18 at the upper end of the barrel is of greaterthickness at the centralpart; anda'bunghole unit 19 is arranged at thecentral part. A reinforcing ring 20 sur-rounds the bung-hole unit andserves to anchor the unit in proper position.

A bung-hole unit 21 i's'provided for the side wall of the barrel, and,it will be noted ythat the inner shell 13 is planar adjacent the unit 21as indicated at 22 so that at this area, the outer. synthetic layer ismaterially thick# ened at 36 in order tocompensate for the length of thebung-hole unit 21. The lower end of the inner shell 13 is arched, and,the. outer surface thereofis covered with a synthetic layer 24 and is ofa thcknesscorrespending tothe load-imposed onA -the lower endA of 'thebarrel. p f y I i( In Fig. 6 is illustrated a modified container inwhich inner shell 13 is provided with reinforcing steel hooplike membersspaced along the Yside wall and such niembers are identified 2 5 andy'26,. The cavity of themember 25 located at lthe central zone of thewall is filled with suitable filler material 28, and, the Acavities ofthe members 26 positioned on opposite sidesof the member 25 `containsimilar ,ller material 27. A,Outer wall 23' of `synthetic materialincludes the metal hoop-like mem-bers2Sand26. l Y Fig. 7 shows a vesselV having a thin-walled inner shell 29 provided withr recesses 30 forbung-hole units. Outer sleeve `31 is formed by casting and -isisuchathickness as to satisfy the requirements which are made `on the vessel.Hoops 32 and end projections 33 are preferably formed during casting orin any other suitable manner vand the end of the bung-hole recess 30 is`surrounded `bycasting flange 34. `In order to strengthen the hoops 32of the outer shell 31, lreinforcing inserts 35 of steel and the like maybe cast in the shell.
